TRACK-ADJUSTING JACK.

Specification of Letters Patent.

Patented Aug. 23, 1910.

To all whom it may concern:

Be it known that we, BENJAMIN F. HACKE'I'I and JOHN J. OWEN, citizens ofthe United States, residing at Willard, in the county of Torrance andTerritory of New Mexico, have invented certain new and usefulImprovements in Track-Adjusting Jacks; and we do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to improvements in trackalining and liftingjacks.

The object of the invention is to provide a jack of this character bymeans of which track rails may be brought into proper alinement or gageand by means of which the rails may be lifted to'the proper. grade orlevel.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional viewof a jack constructed in accordance with the invention; showing the sameengaged with a track rail for the purpose of alining the same; Fig. 2 isa top plan view of the same; Fig. 3 is a side view, showing the mannerof using the jack for lifting a rail; Flg. 4 is a detail perspectiveview of the detachablleI evening block for the foot piece of the acReferring more particularly to the drawings, 1 denotes the body portionof the jack in which is formed a guide channel 2 to receive theadjustable operating bar 3. On one end of the body portion 1 is formedan obliquely disposed wedge shaped foot piece 4, one end of which hasformed thereon an anvil 5 whereby the opposite end may be driven intothe ground to form a stop or abutment against which pressure is appliedwhen the jack is operated. The foot piece 4 is provided on one side witha rail engaging plate 6, the purpose of which will hereinafter appear.

On the inner end of the adjustable operating bar 3 is formed a stop ug 7while on the outer end of the same is secured a rail engaging head 8which is preferably rounded on its outer end, as shown, to fit betweenthe base flange and head of the rail when applied thereto. Onthe outerside of the operating bar 3 is formed a series of ratchet teeth 9 whichare adapted to be engaged by operating pawls 10 and 11 pivotally mountedin the bifurcated head 12 of an operating lever 13, said lever beingpreferably detach'ably engaged with the head 12 by means of a socket 14formed on the head, as shown. The head 12 is pivotally mounted in apertured ears 15 formed on each edge of the open side of the body ortion 1whereby the pawls 10 and 11 earned by the head will work in the channel2 and operatively engage the ratchet teeth 9 of the operating bar toproject the same outwardly. The pawl 11 has formed on its outer end aninwardly projecting hook 16 which engages the teeth 9 of the bar 3 sothat when the operating lever and head are swung in one direction, thehook on the pawl 11 will engage the teeth 9 and when the lever and headare swung in the opposite direction, the pawl 10 will operatively engagethe teeth 9 so that the operating bar 3 is projected forwardly at eachmovement of the lever.

In using the device for alining a track rail, the head 8 is engaged withthe rail and the foot piece driven into the ground thus forming a brace,after which the operating lever is actuated to engage the pawls with theoperating bar, thus projecting the same, as hereinbefore described, andforcing the rail into alinement.

When the jack is employed for lifting a rail, an evening piece 17 isprovided and engaged with the anvil end 5 of the foot piece so that whenthe jack is stood up in position to engage the plate 6, with theunderside of the rail to be raised, the piece 17 will support the outerend of the foot piece in proper osition and will act as a fulcrum onwhich e jack may be rocked in the operation of lifting the track. Ifdesired, the pawls 10 and 11 may be provided with suitable handles 18for disengaging the same from the teeth of the operating bar. The bodyportion of the jack may be also pro vided with a handle 19 by means ofwhich the same may be more readily carried.

It will be noticed that as the foot piece 4 is secured on the body 1obliquely, that the jack will not assume a vertical position when theanvil end of the foot so that when the head 8 is placed under an objectto be lifted the rack bar 3 will stand vertically and the .is employedas in Fig. 3', (as a fulcrum piece), and when it is placed under someobject to be lifted.

' From the foregoing description, taken in 7 connection with theaccompanymg drawings, the construction and operation of the inventionwill be readily understood with-4 out requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claims.

Having thus described our invention, what we claim is:

1. In a jack of the character described, a body portion having formedtherein a guide in said channel, a head on the outer end of said bar,means 'to project the latter, an

oblique foot piece on one end of saidbody portion adapted to be driveninto the ground to form ananchoring brace, a rail enga plate on saidfoot iece, and an evem iig dalock adapted to be etachably engaged withsaid foot piece to hold the jack in an upri ht position. v

2. In a ifting jack, a body, an operating bar slidably mounted therein,means for projecting the same from one end of the body, an ob iquebracing foot on the op osite end of the body and an evener blocketachably engaged with the foot to hold the jack in upright position.

Intestimony whereof we have hereunto set our hands in presence of twosubscribing wltnesses. I
